ENVIRONMENTAL PROTECTION 

AGENCY 

[EPA–HQ–OAR–2023–0460; FRL–11946–03– 

OAR] 

Release of Volumes 1 and 2 of the 

Integrated Review Plan for the National 

Ambient Air Quality Standards for 

Ozone and Related Photochemical 

Oxidants 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of availability and public 

comment period. 

SUMMARY: On or about December 20, 

2024, the Environmental Protection 

Agency (EPA) is making available to the 

public Volumes 1 and 2 of the 

Integrated Review Plan for the National 

Ambient Air Quality Standards for 

Ozone and Related Photochemical 

Oxidants (IRP). The national ambient air 

quality standards (NAAQS) from 

photochemical oxidants are set to 

protect public health and public welfare 

from these pollutants in ambient air. 

Volume 1 of the IRP contains contextual 

background material for the current 

review of the air quality criteria and the 

NAAQS. Volume 2 identifies policyrelevant issues in the review and 

describes key considerations in the 

EPA’s development of the Integrated 

Science Assessment (ISA). The ISA 

provides the scientific basis for the 

EPA’s decisions, in conjunction with 

additional technical and policy 

assessments, for the review of the 

NAAQS, as described in sections 108 

and 109 of the Clean Air Act. 

DATES: Comments must be received on 

or before January 21, 2025.

SUPPLEMENTARY INFORMATION: 

I. General Information 

Written Comments 

Submit your comments, identified by 

Docket ID No. EPA–HQ–OAR–2023– 

0460, at https://www.regulations.gov 

(our preferred method), or the other 

methods identified in the ADDRESSES

section. Once submitted, comments 

cannot be edited or removed from the 

docket. The EPA may publish any 

comment received to its public docket. 

Do not submit to EPA’s docket at 

https://www.regulations.gov any 

information you consider Confidential 

Business Information (CBI), Proprietary 

Business Information (PBI), or other 

information whose disclosure is 

restricted by statute. Multimedia 

submissions (audio, video, etc.) must be 

accompanied by a written comment. 

The written comment is considered the 

official comment and should include a 

discussion of all points you wish to 

make. The EPA will generally not 

consider comments or comment 

contents located outside of the primary 

submission (i.e., on the web, cloud, or 

other file sharing system). Please visit 

https://www.epa.gov/dockets/ 

commenting-epa-dockets for additional 

submission methods; the full EPA 

public comment policy; information 

about CBI, PBI, or multimedia 

submissions; and general guidance on 

making effective comments. 

II. Information About the Documents 

Two sections of the Clean Air Act 

(CAA or the Act) govern the 

establishment and revision of the 

NAAQS. Section 108 directs the 

Administrator to identify and list 

certain air pollutants and then issue ‘‘air 

quality criteria’’ for those pollutants. 

The air quality criteria are to 

‘‘accurately reflect the latest scientific 

knowledge useful in indicating the kind 

and extent of all identifiable effects on 

public health or welfare which may be 

expected from the presence of such 

pollutant in the ambient air . . .’’ (CAA 

section 108(a)(2)). Under section 109 of 

the Act, the EPA is then to establish 

primary (health-based) and secondary 

(welfare-based) NAAQS for each 

pollutant for which the EPA has issued 

air quality criteria. Section 109(d)(1) of 

the Act requires periodic review and, if 

appropriate, revision of existing air 

quality criteria. Revised air quality 

criteria are to reflect advances in 

scientific knowledge on the effects of 

the pollutant on public health and 

welfare. Under the same provision, the 

EPA is also to periodically review and, 

if appropriate, revise the NAAQS based 

on the revised air quality criteria. 

The Act additionally requires the 

appointment of an independent 

scientific review committee that is to 

periodically review the existing air 

quality criteria and NAAQS and to 

recommend any new standards and 

revisions of existing criteria and 

standards as may be appropriate (CAA 

section 109(d)(2)(A)–(B)). Since the 

early 1980s, the Clean Air Scientific 

Advisory Committee (CASAC) has 

fulfilled the requirement for an 

independent scientific review 

committee. 

Presently, the EPA is reviewing the air 

quality criteria and NAAQS for O3 and 

related photochemical oxidants.1 The 

documents announced in this notice 

have been developed as part of the 

integrated review plan (IRP) which is 

developed in the planning phase for the 

review. The documents have been 

prepared jointly by the EPA’s Center for 

Public Health and Environmental 

Assessment within the Office of 

Research and Development and the 

Office of Air Quality Planning and 

Standards within the Office of Air and 

Radiation. These documents will be 

available on the EPA’s website: https:// 

www.epa.gov/naaqs/ozone-o3-airquality-standards, accessible under 

‘‘Planning Documents’’ for the current 

review. 

The IRP for the current review of the 

O3 NAAQS will be comprised of three 

volumes. Volumes 1 and 2 are the 

subject of this notice. Volume 1 

provides background information on the 

air quality criteria and O3 NAAQS and 

may serve as a reference by the public 

and the CASAC in their consideration of 

the subsequent two volumes. Volume 2 

addresses the general approach for the 

review and planning for the integrated 


ddrumheller on DSK120RN23PROD with NOTICES1
104152 Federal Register / Vol. 89, No. 245 / Friday, December 20, 2024 / Notices 

science assessment (ISA). Comments are 

solicited from the public on Volume 2, 

which will also be the subject of a 

consultation with the CASAC Ozone 

Panel, to be announced in a separate 

Federal Register notice. This volume 

identifies policy-relevant issues in the 

review and describes key considerations 

in the EPA’s development of the ISA. 

Volume 3, which is not yet completed, 

is the planning document for 

quantitative analyses to be considered 

in the policy assessment (PA), including 

exposure and risk analyses, as 

warranted. In order that consideration of 

the availability of new evidence in the 

review can inform these plans, the 

development and public availability of 

Volume 3 will generally coincide with 

that of the draft ISA, and it will be the 

subject of a consultation with the 

CASAC Ozone Panel at that time. These 

documents do not represent and should 

not be construed to represent any final 

EPA policy, viewpoint, or 

determination. 

As described above, comments on 

Volume 2 of the IRP should be 

submitted to the docket by January 21, 

2025. A separate Federal Register notice 

will provide details about the CASAC 

Ozone Panel consultation meeting and 

the process for public participation in 

the consultation. The EPA will consider 

the consultation comments and public 

comments on the IRP, Volume 2, in 

preparation of the ISA for O3 and related 

photochemical oxidants. Volume 1 of 

the IRP, also being made available, 

provides background or contextual and 

historical material for this NAAQS 

review.
